Description

Composite weight training machine with adjustable power

This invention is a composite weight training machine with adjustable variable power, especially one that uses the two ends of the steel cable of the transmission mechanism to connect a pulling mechanism at the same time, so that the force applied is equal to the counterweight of the weight block of the damping mechanism, and one end of the steel cable of the transmission mechanism is not connected to the pulling mechanism, so that the load weight of the weight training machine can be adjusted to variable power.

Although the usage of indoor sports equipment is different from that of outdoor sports, at the current stage, various indoor sports equipment in different fields can be used to train muscles in various parts of the body, so that consumers can perform physical training at home or indoors to achieve the purpose of fitness training. Most general weight training machines have the functions of increasing muscle strength, improving body shape and helping to lose excess fat, and are widely used by the general public. The conventional weight training machine must use a weight block selector to select the weight when adjusting the weight, and the weight of the weight is limited by the weight selected by the weight block selector. Therefore, the invention provides a composite weight training machine with adjustable variable power. The weight training machine has a variety of sports types. Each weight training machine for each sports type has at least one damping mechanism, which is connected by two ends of a steel cable of a transmission mechanism with a pulley set. In a pulling mechanism, the force-applying element and the steel cable of the pulling mechanism are directly connected to the steel cable of the transmission mechanism to pull the weight block of the damping mechanism to move upward. The force-applying weight is equal to the counterweight of the weight block of the damping mechanism, and the damping mechanism is converted into a counterweight weight that requires variable-multiple force for force-applying. One end of the steel cable of the transmission mechanism can be unconnected to the pulling mechanism, so that the load weight of the weight training machine can be adjusted to variable-multiple force.

The main purpose of this invention is to provide a composite weight training machine with adjustable variable power. The weight training machine has multiple sports types. Each weight training machine for each sports type has at least one damping mechanism. The two ends of the steel cable of a transmission mechanism with a pulley set are connected to a pulling mechanism, so that the force-applying element and the steel cable of the pulling mechanism directly connect the steel cable of the transmission mechanism to pull the weight block of the damping mechanism to move upward. The force-applying weight is equal to the counterweight of the weight block of the damping mechanism, and the damping mechanism is converted into a counterweight weight that requires variable power for force application. One end of the steel cable of the transmission mechanism can be unconnected to the pulling mechanism, so that the load weight of the weight training machine can be adjusted to variable power.

Please refer to the first figure. This invention provides a composite adjustable variable-power weight training machine 10. The weight training machine 10 includes a frame 1. The frame 1 includes weight training machines 10 for various sports. Each weight training machine 10 for each sports has at least one damping mechanism 2.

Please refer to one of the embodiments shown in the second figure. The weight training machine 10 is provided with two upright vertical rods 11 on the frame 1 and a top rod 12 and a bottom rod 13 located above and below the two vertical rods 11. Two guide rods 14 are provided between the top rod 12 and the bottom rod 13.

The damping mechanism 2 is disposed on the frame 1, and includes a plurality of weight blocks 21 that can move up and down on the two guide rods 14. A fixed head 22 is disposed above the weight block 21, and the counterweight weight of the weight block 21 is W.

A transmission mechanism 3 includes a first steel cable 31, a plurality of fixed pulleys 32, 33, 34 provided on the top rod 12 of the frame 1, and a movable pulley 35 provided on the top of the damping mechanism 2. A connecting bracket set 36 is provided at one end of the first steel cable 31, and the other end of the first steel cable 31 passes over the plurality of fixed pulleys 32, 33 on the upper side of the top rod 12 of the frame 1, then goes around under the movable pulley 35 provided on the top of the damping mechanism 2, and then passes over the fixed pulley 34 on the lower side of the top rod 12 of the frame 1. A suspension member 37 is finally provided at the end of the first steel cable 31, and the suspension member 37 can be selectively coupled to or not coupled to the connecting bracket set 36.

A pulling mechanism 4 includes a second steel cable 41, one end of which is provided with a force element 42, and the other end of the second steel cable 41 passes through a plurality of fixed pulleys 43, 44, 45, 46, 47, 48, 49 provided on the aforementioned frame 1, and the end of the second steel cable 41 is finally connected to the lower end of the connecting bracket assembly 36 of the aforementioned transmission mechanism 3.

Due to the physical properties of the pulley set, the number of fixed pulleys installed in the transmission mechanism 3 and the pulling mechanism 4 will not change the magnitude of the applied force, so the number of fixed pulleys installed in this invention is not limited to the specific embodiments disclosed herein except for the implementation exceptions recorded in this specification.

Please refer to the sixth figure. When the user wants to operate the weight training machine 10, the user can hold the force element 42 and pull it downward. The two ends of the first steel cable 31 of the transmission mechanism 3 can be simultaneously connected to the pulling mechanism 4, so that the force element 42 and the second steel cable 41 of the pulling mechanism 4 directly link the first steel cable 31 of the transmission mechanism 3 to pull the weight block 21 of the damping mechanism 2 upward. The force weight F of the force element 42 held downward and pulled is equal to the counterweight weight of the weight block 21 of the damping mechanism 2. The amount W is F=W, and the force element 42 is displaced in the opposite direction by hand, so that the weight block 21 of the damping mechanism 2 returns to its original position. In this way, the hand, chest muscle or back muscle training is performed by repeatedly pulling up and down, and the damping mechanism 2 is converted into a counterweight weight that requires variable power for force application. One end of the first steel cable 31 of the transmission mechanism 3 can be unconnected to the aforementioned pulling mechanism 4, so that the load weight of the weight training machine 10 can be adjusted to a variable power. The force weight F=1/2W when holding the force element 42 and pulling it downward.

Please refer to the seventh figure, which is another embodiment of the weight training machine 10 of the invention. The weight training machine 10 is a weight training machine 10 for training both feet. In addition to the damping mechanism 2 and the transmission mechanism 3, the weight training machine 10 is provided with a two-way mechanism 5, a force-applying element 56 driving the two-way mechanism 5, and a pulling mechanism 6 linked to the two-way mechanism 5 on the frame 1. A seat 7 is provided on the outer side of the frame 1, and the seat 7 includes a force-bearing element 71.

The two-way mechanism 5 is arranged on the frame 1, and is provided with an upper cam 51, a lower cam 52 and a rotating wheel 53 on the same shaft. The upper cam 51 and the lower cam 52 are both provided with a fixed end 510, 520 at both ends. The rotating wheel 53 can drive the upper cam 51 or the lower cam 52 separately. The rotating wheel 53 is provided with a connecting rod 54 extending from the upper and lower parts respectively. An adjusting seat 55 is provided on one end of the connecting rod 54, and a force applying element 56 is provided on the adjusting seat 55.

Please refer to Figures 7 and 8. The pulling mechanism 6 includes a third steel cable 61 and a fourth steel cable 62. One end of the third steel cable 61 is fixed on the top rod 12 of the aforementioned frame 1, and then goes down around the upper wheel 631 of a pulley set 63. The end of the third steel cable 61 is finally connected to the lower end of the connecting bracket set 36 of the aforementioned transmission mechanism 3. One end of the fourth steel cable 62 is fixed to the fixed end 510 of the aforementioned upper cam 51, and the other end of the fourth steel cable 62 passes through the multiple fixed pulleys 64, 65, 66 provided on the aforementioned frame 1 and the lower wheel 632 of the aforementioned pulley set 63 and multiple fixed pulleys 67, 68, 69. The end of the fourth steel cable 62 is finally connected to the fixed end 520 of the aforementioned lower cam 52.

Please refer to the first and eighth figures. When the user wants to operate the weight training machine 10, the user (not shown in the figure) sits on the seat 7 and uses both feet to apply force to the force-applying element 56. The upper body of the user will be unstable. Therefore, the user needs to use the aforementioned force-bearing element 71 to achieve body balance. The force-applying element 56 drives the two-way mechanism 5. When the upper cam 51 or the lower cam 52 of the two-way mechanism 5 rotates, the two ends of the first steel cable 31 of the aforementioned transmission mechanism 3 are simultaneously connected to the aforementioned pulling mechanism 6, so that the pulling mechanism 6 is directly connected to the transmission mechanism 3. The first steel cable 31 of the transmission mechanism 3 pulls the weight block 21 of the damping mechanism 2 upward. The force F applied by the two feet to the force element 56 is equal to the counterweight W of the weight block 21 of the damping mechanism 2, that is, F=W. The damping mechanism 2 is converted into a counterweight that requires variable-power force. One end of the first steel cable 31 of the transmission mechanism 3 can be unconnected to the pulling mechanism 6, so that the load weight of the weight training machine 10 can be adjusted to a variable-power force. The force F applied by the two feet to the force element 56 is 1/2W.

Please refer to another embodiment of the pulling mechanism 8 in Figure 9. The pulling mechanism 8 includes a fifth steel cable 81 and a sixth steel cable 82. One end of the fifth steel cable 81 is fixed to the fixed end 510 of the upper cam 51, and the other end of the fifth steel cable 81 passes through the plurality of fixed pulleys 83, 84, 85 and the upper pulley 891 of a pulley set 89 provided on the frame 1. The end of the fifth steel cable 81 is finally connected to the lower end of the connecting bracket set 36 of the transmission mechanism 3. One end of the sixth steel cable 82 is fixed to the bottom rod 13 of the frame 1, and the other end of the sixth steel cable 82 passes through the lower pulley 892 of the pulley set 89 and the plurality of fixed pulleys 86, 87, 88. The end of the sixth steel cable 82 is finally connected to the fixed end 520 of the lower cam 52.

In summary, the invention provides a composite adjustable variable-power weight training machine 10, which has multiple sports types. Each type of weight training machine 10 has at least one damping mechanism 2. The two ends of a steel cable of a transmission mechanism 3 with a pulley set are connected to a pulling mechanism 4, so that the force element 42 of the pulling mechanism 4 and the steel cable are directly connected to the transmission mechanism 3. The steel cable of the driving mechanism 3 is used to pull the weight block 21 of the damping mechanism 2 upward, and the applied force F is equal to the counterweight weight W of the weight block 21 of the damping mechanism 2. The damping mechanism 2 is converted into a counterweight weight that requires a variable force. One end of the steel cable of the driving mechanism 3 can be unconnected to the pulling mechanism 4, so that the load weight of the weight training machine 10 can be adjusted to a variable force.
